No more silent failures
You might monitor jobs that are running, or take too long to finish. What about jobs that quietly fail? OnlineOrNot alerts you when your cron jobs fail to trigger.
Simple, quick setup.
Create a check using your cron expression, OnlineOrNot gives you a URL to curl, and you get alerts whenever your cron job fails to trigger.
Instant alerts.
Alerts in the tools you already use: Email, SMS, Slack, Discord, Incident.io, PagerDuty, OpsGenie, Grafana OnCall, Spike, and more.
Private, integrated status pages.
Share status updates with your teammates and internal stakeholders with a private status page.
Public API & Open-source CLI
You can use our public API to integrate OnlineOrNot data into your own systems, or use our open-source CLI to check status from your terminal.
On-call integrations.
Already using an On-call tool like PagerDuty, Incident.io, or Opsgenie? OnlineOrNot natively supports sending alerts to them.

    • OnlineOrNot has been absolutely fantastic for my bot, Noti. It completely transformed the way I monitor online services.

      The real-time notifications keep me in the loop about any downtime, allowing me to take immediate action. If you're looking for a reliable way to monitor your project's status, I highly suggest using OnlineOrNot.

    • Bet on indie hackers 🚀

      I tried @RozenMD's OnlineOrNot uptime monitoring, and for a few days got notifications of 2min down time.

      I thought that OnlineOrNot was wrong as Uptime Robot wasn't reporting anything.

      Turns out it was the other way around.

    • We've been using OnlineOrNot and it has been a life saver.

      It, by far, has been one of the most responsive uptime services we've tried and it only gets better and better as time goes on.

    • I just set up some site aliveness checks for @Archium_io with @RozenMD's OnlineOrNot.

      Took me less than five minutes and it was completely self-explanatory, not to mention gorgeous. Seriously good experience.

      Great job, Max! 👏👏

    • OnlineOrNot by @RozenMD is all one needs

      It is easy to set up and very reliable. I have been using it for almost an year now.

    • I'm using OnlineOrNot to monitor my @cloakist customers' sites, so I can respond quickly if they stop working

      Love it. Super clean interface, very intuitive. Particularly impressed at how it can wait for full page load

      Thanks @RozenMD for making this awesome tool!
